After watching a movie, its the feeling you get which makes you feel like it was one of the best movies you've ever seen. You talk about it the whole car ride home claiming it was amazing, but the next day you realize it was just an average movie.

Dude 1: holy crap that movie was amazing with all the actions parts!!

Dude 2: I know we have to watch it again!!!

Next Day

Dude 1: Yea, you know it was an ok movie. I dont wanna see it again.

Dude 2: Yea the movie tickets are so expensive anyways no one wants to waste their money. I guess we were just on a movie high.
